Salamander Active Directory supports Google’s Cloud Identity

Google’s Cloud Identity is a free identity and access management cloud solution that provides a robust set of capabilities to manage your users online. These managed identities provide easy and secure access to all Google products and a large catalogue of third-party applications.

It is implemented as a free license which used instead of a standard G Suite license. Cloud Identity users will not have access to the G Suite core services unless you assign them a G Suite license.
